The General Motors Acceptance Corp. is increasingly counting on its mortgage and insurance units to bring in profits, not its auto financing.

Though the carmaker has enjoyed a boost in sales with its summer discounts, GM is still trying to climb out of its slump, and it looks like the GMAC mortgage and insurance is going to help, according to The Detroit News.

GMAC’s net income for its financing operation reported a drop $74 million, or 16.4 percent. However, the company’s mortgage earnings increased $19 million, while its insurance arm gained $25 million. That tandem helped GMAC secure an overall decline in net income of just 3.4 percent. Second quarter reports showed the mortgage and insurance units representing 54 percent of GMAC’s profit.

Those profits are trying to make up for losses such as the $1.2 billion GM’s North American auto business lost in the second quarter. This year alone that operation has lost $2.5 billion.

On the other hand, GMAC’s residential mortgage unit, Residential Capital Corp., was able to raise $4 billion in the unsecured bond market because of its steady profits.
